WRENCH Filed June 4 1934 v TORNEY Patented July 9, 1935 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to a wrench and more especially to a quick adjusting wrench known as the sliding jaw type.

The primary object of the invention is the provision of a wrench of this character, whereinthe sliding jaw carries a hand actuated slidably adjustable latching bolt which permits of the looking of the sliding jaw with relation to the stationary jaw for the clamping of a piece of work, the sliding adjustment of the bolt being to permit close adjustment of the sliding jaw with relation to the work and also permits of the quick and easy latchingand unlatching of said sliding jaw at the will of the user of the wrench.

Another object of the invention is the provision of a wrench of this character which is extremely simple in its construction, thoroughly reliable and; effective in its purpose, strong, durable, highly practical, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation of a wrench constructed in accordance with the invention and being partly in section with the latching bolt in latching position.

Figure 2 is a view similar to Figure 1 showing the latching bolt in releasing position.

Figure 3 is an edge elevation.

Figure l is a section on line 4-4 of Figure 1.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to thedrawing in detail, the wrench comprises a shank 5 having formed therefrom at one end the handle 6 and at the other end is provided a stationaryjaw '1. Upon the shank 5 is carried the slidable jaw 8, it being formed with a sleeve-like portion 9 which embraces the shank 5 for the slidable connection thereof.

The inner longitudinal edge of the shank 5 is provided with a toothed rack I0, while formed in.

the sliding jaw parallel with the rack and on the side next thereto is a socket II which opens through the outer end edge l2 of said sliding jaw and accommodates a slidable and rotatable latching bolt l 3. The outer end of the bolt I3 is formed with a curved latching tip or terminal l4 adapted for selective engagement between any of the teeth of the rack it! so as to lock the sliding jaw 8 in adjusted position.

The sliding jaw 8 has formed therein and intersecting the socket or way II for the bolt l3 a re- 5 cess l5 for accommodating a turning sleeve I6, the latter receiving the said bolt l3 and being fitted with a set screw I! which binds against the bolt to prevent displacement by sliding movement in the socket l l on adjustment in the use of said 10 set screw.

The'handle end of the shank 5 is formed to provide a screw driver tip or bit l8 so that the wrench can be utilized as a screw driver, or prying tool. 15

In the use of the Wrench, assuming that the bolt [3 is in latching position with the rack l0 and it is desired to adjust the sliding jaw 8, the turning sleeve I5 is rotated in the recess I5, thus throwing the tip or terminal M of the bolt I3 to a 20 disengaged position with the rack 10 and thus freeing the sliding-jaw 1 so that it can be moved to a piece of work to be held between the stationary jaw l and sliding jaw B. Thereupon, the turning sleeve I6 is rotated to bring the tip or 5 terminal M of the bolt 13 into engagement with the rack l0 and thus locking the sliding jaw related with the work. If accurate adjustment is desired the set screw I6 can be loosened and by sliding the sliding jaw 8 with relation to the bolt 30 IS the said sliding jaw can be brought into close contact with the work to be operated upon. Thereafter, the set screw I1 is worked home against the bolt to hold the same fixed in the sliding jaw. 35

From the foregoing it is believed that the ad-. vantages and novel features of the invention will be readily understood and, therefore, further detailed description is deemed unnecessary and. omitted.

What is claimed is:

In a wrench, a sliding law, a toothed rack, a fixed jaw on the rack and cooperating with the sliding jaw, a turning sleeve fitted in the sliding jaw, a latch bolt slidably fitted in said turning 5 sleeve and providing the journal therefor in said sliding jaw, a keeper tip turned from the bolt and engageable with the rack beyond the sliding jaw, and means for making fast the bolt in said sleeve for the turning ofv the bolt therewith to bring 5 its tip into and out of engagement with the rack.
